Add option to automatically promote developers to maintainers in the project they create

Problem to solve

When developers create a new project in a group, they have to wait for a maintainer of the group to create the master branch, or to give them permissions on the project.

I'd like an option so when developers create a project they automatically become maintainer of that project.

Further details

We are a consulting company. We apply the principle of least privilege for the group permission, so on the group level there are just a couple of maintainers, while all the others are just developers.

However, we create a lot of repositories for PoCs, and we promote developers to maintainers there, so everyone is responsible for the PoC is working on.

At the moment, every time developers creates a repo, they have to ping a maintainer to give them privileges.

Proposal

Create a flag in the group setting to allow "autopromotion" when you create a branch.

There should be an advice that in this way your "group secret variables for CI" aren't secret anymore. We don't use them, so we personally don't have any downside I can think of for such a feature
